Originally a sub-unit of the idol group Sakura Gakuin, [=BabyMetal=] (also stylized as BABYMETAL) was formed by the members of the Heavy Music Club of Sakura Gakuin, under the concept of a fusion of "heavy metal and idol music". [=BabyMetal=] released their first single "BABYMETAL Kiba of Akiba" in March 2012, reaching the 3rd place in the Oricon indie charts and number one in the Tower Records Shibuya weekly indie ranking. However, it wasn't until they released their second single, [[http://www.youtube.com/watch?v=2IzR_ClTE8Y "Headbanger!!"]], that they became popular outside of Japan. The video went viral quickly and the sub-unit managed to become a stand-alone group. In 2014 they did a 2-day Budoukan concert and released their first album.

Compare and contrast to Music/KyaryPamyuPamyu for a similar Internet phenomenon, although on a smaller scale in [=BabyMetal=]'s case.

!!Tropes that apply to [=BabyMetal=]
* AscendedExtra: They're even more popular than their parent group, Sakura Gakuin.
* ButNowIMustGo: Averted. Sakura Gakuin only accepts members under 15 years old, and when the current members reach this age, they must graduate. When Suzuka became 15, she left the main group, but the management made [=BabyMetal=] a separate unit, and they'll still be active.
* ChildProdigy: Yui and Moa were talented enough to join Sakura Gakuin at the age of 11 (and produce ''Doki Doki☆Morning'' one year later). And before Sakura Gakuin, Suzuka was in a group called Karen Girl's doing the opening theme of ''Manga/ZettaiKarenChildren''. And that's not counting the other stuff they've done...
* CreepyCoolCrosses: They use it a lot. Special mention goes to Suzuka's 16th birthday, when she was ''crucified''.
* DarkerAndEdgier: Compared to other idol groups.
* EarlyInstallmentWeirdness: Their first song, ''Doki Doki☆Morning'', had a more distinct "idol-like" sound than their following songs.
* [[ExcitedShowTitle Excited Song Title!]]: Their song ''Ii ne!''.
* GirlishPigtails: Moa and Yui's usual hairstyle. Suzuka started out having these too.
* HeWhoMustNotBeSeen: The musicians wear skeleton costumes in the music videos and while appearing in public. Except in ''Megitsune''... where they wear long black wigs and masks.
** HeWhoMustNotBeHeard: When the musicians themselves (including the producer) get interviews, all they do on-screen is mumble and subtitles of what they're actually trying to say are shown.
* HimeCut: When they let down their hair. Suzuka plays it the straightest (literally too), and she's actually done so in certain music videos such as ''Megitsune''.
* IconicOutfit: Their outfits from ''Headbanger!!'', featured in the picture to the right.
** Also the musicians' skeleton costumes.
* IdolSinger
* {{Kawaiiko}}: Moa and Yui.
* {{Kitsune}}: The main theme of ''Megitsune''.
** The theme of the group itself, with its fox sign. They're always seen doing it, such as in the image above.
* TheLeader: Suzuka. Also the FaceOfTheBand.
* LuckyCharmsTitle: ''Doki Doki☆Morning'', ''Uki Uki ★ Midnight''.
* MindScrew: What this idol group is to metal purists. Though many of them somehow like the group...
* MohsScaleOfRockAndMetalHardness: On average, a hard 6 to a soft 7, though "Megitsune" is a borderline 8.
* NeoclassicalPunkZydecoRockabilly: Combines the hardness and energy of heavy metal with the catchiness and appeal of J-pop and a VisualKei-influenced sensibility.
* PunctuatedForEmphasis: ''Ijime, Dame, Zettai'' (''No, More, Bullying'') is a strange example.
* SongStyleShift: "Iine!" has a ''[[TrapMusic Trap]]'' break near the middle, complete with hoodies, GratuitousEnglish, and Music/KanyeWest [[http://1.bp.blogspot.com/_txdFVAWpc94/TOKwqIGfagI/AAAAAAAAA4o/JMPJAXyX6xY/s640/kanye_west_daft_punk_stronger_01.jpg sunglasses.]] [[http://www.youtube.com/watch?v=qVdBBOpSoN4&t=1m33s We are completely serious.]] Apparently it's done as a TakeThat to SwagRap.
** "Uki Uki ★ Midnight" has a {{Dubstep}} break, [[http://www.youtube.com/watch?v=W-2Z_kQpdW0&t=1m36s also near the middle.]]
* SpellMyNameWithAnS: ''Ii ne!'' faces the same problem as ''[[Music/{{Vocaloid}} Ievan Polkka]]''. Three guesses on what that problem is and the first two don't count.
* TitleScream[=/=]MetalScream: ''HEADBANGEEEEEEEEER!!!''
* TomboyishPonytail: Suzuka's usual hairstyle.
* [[WidgetSeries Widget Musicians]]: Three {{Idol Singer}}s mix pop music with Music/HeavyMetal. It works and it's... ''[[CrowningMusicOfAwesome it's totally awesome]]''. Oh, UsefulNotes/{{Japan}}...
